ARNOVITZ IVOLFF, OF NEIV YORK, N. Y.

GAS HEATER OR RADIATOR.

SPECIFICATION forming part of Letters Patent No. 466,958, dated January12, 1892.

Application led August 3l, 1891.

.To all whom it may concern.-

3e it known that I, ARNOVITZ WOLFF, a citizen of the United States,residing in the city, county, and State of New York, have nvented a newand useful Improvement in Gas Heaters or Radiators, of which thefollowing is a specification.

My invention relates to a compact and portable heateror radiator forwarming rooms in buildings by gas-flames.

In carrying out my invention I employ a base and top that are connectedtogether, and between them are vertically placed sheetmetalradiating-tubes in which are gas-burners. These radiating-tubes haveframes with mica, through which the light of the gas-flames can be seenand by which a cheerful appearance is imparted to the room in which theheater is located. These radiating-tubes also have openings opposite theinternal burners, through which said burners are lighted, and openingsat the upper ends for the escape of the heated air. I prefer to place afalse bottom within the base, so that the light of the gas-flames doesnot shine upon the oor and downward radiation is intercepted. The openings for lighting the burners have covers, which are connected by a rodand are adapted to be lifted together to successively light the burners.

In the drawings, Figure 1 is a vertical section and partial elevation ofmy improvedrievice. Fig. 2 is a cross-section at o: and Fig. 8 is asectional plan at y y. Y

d represents the base, which is preferably of cast metal more or lessornamental and provide2d with collars ce' and an internal iange at a brepresents a flat cast-metal top plate with collars b, and c are tubesof sheet metal, such as Russia iron, which at their respective ends fitover the collars c/ b' and constitute the heat-radiating tubes.

An imperforate plate or sheet of metal d' covers the top b, and anopen-work ornamental top or coveresurmounts the heater or radiator, andscrew-ended tie-rods or tubes 1, 2, 3, and -l at the respective cornersfirmly bind and hold the top e and base d, into which they screw, andthe intermediate parts together.

A gas-pipe f passes into and lengthwise Serial No. 404,189. (No model.)

through the radiator-base a, and said pipe is burner being within andcentral of each tube c, and the openings at c2 afford a means of 55reaching and lighting the burners f2, as they are adjacent to saidburners. The pipe f may be flexibly or rigidly connected to the maingas-supply. The oblong frames 7L, having lugsrat their lower ends, areto be secured vertically at openings made in the tubes c, and theseframes are adapted to hold mica, and the light of the gas-flames isvisible and passes through said mica into the apartment where the heateris located to shed a cheerful light in said apartment. To the lugs ofeach of these frames 7L are hinged small plates fi, adapted to fit overand close the openings c2. These plates i have perforated lugs, throughwhich passes a rod by means of which all 7o thrown down upon the iioorand to interrupt 8o radiated heat. The serrated edges of the plate 7callow for the admission into the base a of atmospheric air for thegas-flames.

I provide openings c in opposite sides of the sheet-metal tubes c attheir upper ends,

and these openings provide for the escape into the apartment of theheated air from. within the tubes c. The radiated heat outside the tubesc also ascends and causes a circulation and heating of the air of theapartment.

I claim as my invention-- 1. The combination, in a gas heater orradiator, with a base and a gas-pipe passing through the base and havingburners, of vertical sheet-metal tubes c, rising from said base andhaving upper openings o for the escape of heated air and lower openingsc*2 to allow for lighting the burners, and an imperforate plate closingthe upper ends of the tubes c, substantially as and for the purposes setforth.

2. The combination, in a gas heater or radiator, with a base and agas-pipe passing ICQ through the base and-having burners, of vertiealsheet-metal tubes c, rising from said base and having upper openings ofor the escape of heated air and lower openings c2 to allow for lightingthe burners, frames connected upon the faces of said tubes c and havinglugs -at their lower ends, and the plates or frames 1', Connected tosaid lugs and adapted to cover the openings c2, and an imperforate plateclos.- f

i-ng the upper ends of the tubes c, substantially as and for thepurposes set forth.

3. The combination, with the base and Vtop and the gas pipe and burners,of the vertical sheet-metal tubes c, the frames h, vwith mica connectedtherewith and having lugs at their collars .and having openings eneartlieir upper vendsythe imperforate plate d, covering the tops ofsaid tubes e, the open-work top e, resting upon the plate d, the cornertie-rods connecting the base a and top e, and the plate 7c within thebase, having turned-up serrated edges,-and means for securing said platetov the base, substantially as set forth.

5. Theoombina-tion, in a gas heater or radiator, with y'a base havinglegs7 of vertical sheetinetal tubes c, rising from said base, a gaspipepassing through saidbase and having burners at the lower ends of thetubes c, and a bottom plate 70, fitting freely Within and connected tothe base and having turn ed-up edges around which'V air passes*l tortheburners, whereby. downward radiation is-` prevented, substantiallyas specified'.`
